Description

Technical Field

[0001] This utility model relates to the field of steel pipe production technology, and in particular to a U-shaped steel pipe shelf tooling. Background Technology

[0002] Steel pipes play an indispensable role in modern industry. Their high strength, good ductility, and corrosion resistance make them the preferred material in construction, transportation, machinery manufacturing, and energy sectors. Based on different application requirements and production technologies, steel pipes are mainly divided into two types: seamless steel pipes and welded steel pipes.

[0003] To further enhance the corrosion resistance of steel pipes and extend their service life, zinc-nickel diffusion coating is widely used in steel pipe surface treatment. This process effectively prevents corrosion of the steel pipe substrate by forming a dense zinc-nickel alloy layer on the pipe surface. However, to ensure the quality of this diffusion coating, the steel pipe must remain intact throughout the entire process, and uniform heating must be ensured, which is crucial for the performance of the final product.

[0004] Traditionally, steel pipes are typically introduced into the carburizing furnace in batches or as bare packages during this surface treatment process. This approach presents several problems: the weight of the steel pipes themselves and the pressure generated by stacking them can easily cause them to bend or flatten during the rotary heating process; furthermore, steel pipes stacked close together may result in inconsistent carburizing layer thickness due to uneven heat distribution. Utility Model Content

[0005] The purpose of this utility model is to provide a U-shaped steel pipe shelf fixture that can evenly stack steel pipes, avoiding bending or flattening deformation of the steel pipes during the rotation heating process, while also ensuring uniform heat distribution of the steel pipes and achieving uniform penetration.
